MBWorld.org Forums - Radio & CD stacker not working after disconnecting battery.

My radio and CD Stacker are no longer working on my 1999 C200 elegance W202 after I disconnected the battery to try and solve another problem I have with my front window which is getting stuck and essentally not working. The suggestion was to reset window by disconnectting the battery. It didnt fix the window problem and has now created this issue. I have no clue how to fire up the Radio/Cd player. It is getting power as some numbers do appear on the radio screen but I cant get any stations nor get any CD's to work.Maybe there is a combination of buttons tp press. Please help.
